Question: How Can I plot the data result of a program?

hello!, How can i to plot the next data in a 2D plot?. it is the result of a loop for.... do....while. I had tried with pointplot anda dataplot, but must be something wrong!

with(plots);
for i from 1.73205080756887853 by 0.5e-2 while i < 2.87500000000000000 do roll := i; f1max := NLPSolve(f1, {f2 = i}, x1 = 0 .. 2, x2 = 0 .. 3, method = sqp, maximize = false); c := op([1], f1max), print(c, roll) end do; plot(roll, c);
